Abstract.

A pentagon-shaped undoped BaTiO3 crystal was used to construct a high-quality mutually pumped phase conjugator. It yields two very stable phase-conjugate outputs (±1.7% fluctuation in intensity) with high reflectivity (the highest ≈45%) when the two incident beams are of equal intensities. The response time of the conjugator is rather fast (≈3 s) and the tolerance of the acceptance angle is large too (≈100°). Fine structures (35 μm) in an image, after passing through a phase aberrator, can be recovered by the conjugate waves yielded by this conjugator.
